This example illustrates the properties and criteria of similar right triangles. It involves core math concepts like trigonometric functions, geometric constructions, and equation solving. GeoGebra commands such as segment, point, orthogonal line, intersect, and angle are used in the construction. Suitable for high school mathematics teaching and geometric construction practice.
